$maxScan

$maxScan

Constrains the query to only scan the specified number of documents when fulfilling the query. Use one of the following forms:

db.collection.find( { <query> } )._addSpecial( "$maxScan" , <number> )
db.collection.find( { $query: { <query> }, $maxScan: <number> } )

Use this modifier to prevent potentially long running queries from disrupting performance by scanning through too much data.
